There are several key factors in determining whether it is time for you to replace your roof. Problems signs can be recognized from inspecting the interior and exterior of your house by looking for the following common issues of a deteriorating roof, such as:
 

1) Leaky Roof

From the interior, round yellow/brown spots on your ceiling are a good indication your roof is leaking. Depending on the size of the spots and how fast it is growing in size shows the severity of the roof leak.

2) MISSING SHINGLES  

Shingles can disappear due to improper installation/fastening. Can be blown off in extreme wind storm conditions.

3) CURLING SHINGLES/CEDAR SHAKES -

As shingles/shakes age they absorb more moisture and as more is absorbed and retained in the shingle, it results in the edges beginning to curl up

4) Cracked/Split Tiles + Cedar Shakes

Shakes and tiles can crack as a result or tension build up that comes with house settlement over time, as well as other factors such as inexperience walking on the roof or something being dropped on the roof.

5) BLISTERING -

Results from increased moisture in the shingle and poor ventilation in the roof area.

6) MISSING GRANULES -

Normally a certain number of granules will be loose, especially after application. On aging shingles, this indicates the need for replacement.

7) ROTTING -

Results when there has been complete failure of an area that has allowed water/moisture to penetrate into the roof deck for an extended period of time. The severity of the damage will depend on the amount of time the water has been penetrating through.

8) TAR & GRAVEL ROOFS -

As a tar & gravel roof ages, the tar can eventually to crack due to several things such as house settlement, expansion/contraction from hot to cold conditions and regular wear and tear. During the inspection we check for cracking, blistering, surface erosion and wrinkling. Look for cracks at roof joints, near roof mounted structures and the flanged metal strip along the roof perimeter.
